I686-elf-gcc «Ошибка: неверный суффикс инструкции для 'push'/'pop'» [закрыто] ⇐ Linux

[Anonymous]

Я следую руководству по базовой версии OSDev Wiki и пытаюсь скомпилировать файл kernel.c с помощью
i686-elf-gcc -ffreestanding -O2 -m32 -c kernel.c -o kernel.o

но я постоянно получаю следующие сообщения ассемблера:

Я в замешательстве, потому что точно знаю, что я 1. правильно построил свой компилятор и 2. правильно написал свой код.
Пожалуйста, помогите мне!
